The goal in
530 Eco Shooter is to clear each level with the highest score possible. Earn points by shooting cans while travelling on a pre-determined path. Hit cans while they are still in the air to gain more points. Destroyed cans will turn into Can Energy. Vacuum up the Can Energy to replenish your ammo. If a can hits you, you will lose a portion of your Can Energy from your Energy Gauge. If you run out of Can Energy, the game is over. Any remaining Can Energy at the end of a stage will be converted into bonus points and added to your score.
Usually, cans that are more difficult to hit produce more Can Energy when destroyed.
